4.3 Jumpers1. Clear RTC RAM (CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in the CMOS, which includes the system setup information such as system passwords.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord. 2. Remove the battery.

3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5-10 seconds, then move the cap back to pins 1-2.

4. Re-install the battery. 5. Plug the power cord and turn ON the computer. 6. Hold down the <Del> key during the boot process and enter BIOS

setup to re-enter data.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure.

5-2 Chapter 5: BIOS setup5-2

5.1 Managing and updating your BIOSThe following utilities allow you to manage and update the motherboard Basic Input/Output System (BIOS) setup.

1. ASUS EZ Flash: Updates the BIOS using a floppy disk, or the motherboard support CD during POST.

2. ASUS AFUDOS: Updates the BIOS using a bootable floppy disk in DOS mode.

3. ASUS CrashFree BIOS 2: Updates the BIOS using a bootable floppy disk or the motherboard support CD when the BIOS file fails or gets corrupted.

4. ASUS Update: Updates the BIOS in Windows® environment.

Refer to the corresponding sections for details on these utilities.

Save a copy of the original motherboard BIOS file to a bootable floppy disk in case you need to restore the BIOS in the future. Copy the original motherboard BIOS using the ASUS Update or AFUDOS utilities.


5.1.1 ASUS EZ Flash utilityThe ASUS EZ Flash feature allows you to update the BIOS without having to go through the long process of booting from a floppy disk and using a DOS-based utility. The EZ Flash utility is built-in the BIOS chip so it is accessible by pressing <Alt> + <F2> during the Power-On Self Tests (POST).

To update the BIOS using EZ Flash:

1. Visit the ASUS website (www.asus.com) to download the latest BIOS file for the motherboard and rename the same to P5945GCX.ROM.

2. Save the BIOS file to a floppy disk, then restart the system.3. Press <Alt> + <F2> during POST to display the following.

EZFlash starting BIOS updateChecking for floppy...

4. Insert the floppy disk that contains the BIOS file to the floppy disk drive. When the correct BIOS file is found, EZ Flash performs the BIOS update process and automatically reboots the system when done.

EZFlash starting BIOS updateChecking for floppy...Floppy found!Reading file “P5945GCX.rom”. Completed.Start erasing.......|Start programming...|Flashed successfully. Rebooting.

• Do not shut down or reset the system while updating the BIOS to prevent system boot failure!

• A “Floppy not found!” error message appears if there is no floppy disk in the drive. A “P5945GCX.ROM not found!” error message appears if the correct BIOS file is not found in the floppy disk. Make sure that you rename the BIOS file to P5945GCX.ROM.

5-4 Chapter 5: BIOS setup

5.1.2 AFUDOS utilityThe AFUDOS utility allows you to update the BIOS file in DOS environment using a bootable floppy disk with the updated BIOS file. This utility also allows you to copy the current BIOS file that you can use as backup when the BIOS fails or gets corrupted during the updating process.

Copying the current BIOSTo copy the current BIOS file using the AFUDOS utility:

1. Copy the AFUDOS utility (afudos.exe) from the motherboard support CD to the bootable floppy disk you created earlier.

2. Boot the system in DOS mode, then at the prompt type:

afudos /o[filename]

where the [filename] is any user-assigned filename not more than eight alphanumeric characters for the main filename and three alphanumeric characters for the extension name.

• Make sure that the floppy disk is not write-protected and has at least 600 KB free space to save the file.

• The succeeding BIOS screens are for reference only. The actual BIOS screen displays may not be exactly the same as shown.

Main filename Extension name

A:\>afudos /oOLDBIOS1.ROM

5.2 BIOS setup programThis motherboard supports a programmable Low-Pin Count (LPC) chip that you can update using the provided utility described in section “5.1 Managing and updating your BIOS.”

Use the BIOS Setup program when you are installing a motherboard, reconfiguring your system, or prompted to“Run Setup.” This section explains how to configure your system using this utility.

Even if you are not prompted to use the Setup program, you can change the configuration of your computer in the future. For example, you can enable the security password feature or change the power management settings. This requires you to reconfigure your system using the BIOS Setup program so that the computer can recognize these changes and record them in the CMOS RAM of the LPC chip.

The LPC chip on the motherboard stores the Setup utility. When you start up the computer, the system provides you with the opportunity to run this program. Press <Del> during the Power-On Self-Test (POST) to enter the Setup utility. Otherwise, POST continues with its test routines.

If you wish to enter Setup after POST, reboot the system by doing any of the following procedures:

• Restart using the OS standard shut-down procedure.• Press <Ctrl>+<Alt>+<Del> simultaneously. • Press the reset button on the system chassis. • Press the power button to turn the system off then back on.

• The default BIOS settings for this motherboard apply for most conditions to ensure optimum performance. If the system becomes unstable after changing any BIOS settings, load the default settings to ensure system compatibility and stability. Select the Load Default Settings item under the Exit Menu. See section “5.7 Exit Menu.”

• The BIOS setup screens shown in this section are for reference purposes only, and may not exactly match what you see on your screen.

• Visit the ASUS website (www.asus.com) to download the latest BIOS file for this motherboard.

Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to force reset from a running operating system can cause damage to your data or system. We recommend to always shut-down the system properly from the operating system.

The Setup program is designed to make it as easy to use as possible. Being a menu-driven program, it lets you scroll through the various sub-menus and make your selections from the available options using the navigation keys.
